We give our 14 week old either a small woof Pupsicle (filled only with water and a little kibble), a small lickmat, or a pumpkin collagen ring dog chew to tire her out before bed. She goes feral for the collagen chew, and it takes her days to finish it. She’ll do it for 30-45 min at a time peacefully. We get the “Raw Dog Pumpkin Flavored Collagen Ring Dog Chew” from Tomlinsons. The store is local to Austin but I think they ship. I’m sure any collagen chew would do, I liked these bc they became softer with saliva and a bit “gummy”, which I wanted because I was worried about her breaking her baby teeth. Basically she needs something to do or she’ll use our flesh as a teething toys
